Structures of Vitamin K wrong

By my textbooks (1974 & 1983) the structure of Vitamine K2 is wrong. The repeating part should have n=6, and the double bond within the repeat is missing. I think vitamin K1 might be missing a non-repeating methylene just before the repeating part starts. Can anyone verify that for me?
